' lVhile the method which forms one branch of my invention may obviously be practised independently of the particular mechanism here shown, it will conduce to brevity in this specification it l describe it in connection with the manner of oaeration ot the Inachine here disclosed. l shall, therefore, first describe that machine in order that its operation and consequently the method en emplified thereby may be abundantly clear.

The machine will he described in connection with its use for wrapping a group of tire shoes, although obviously its field of use is not restricted thereto. Cha acterized briefly, the operation of the machine chosen as illustrating my invention is to wrap a sheet about one circumference and the ends ot' the groupl of tires, provision being'niade for conforming the wrapping sheet to the group, and to seal the package by a sealing strip applied 'to the other circumference, the tires being compressed within the package to tension the wrapping.

Referring to the rrar'i the machine shown herein as illustrating the invention comprises a diskdike table l (Figs. l to 5) having radial fingers arranged adjacent the. periphery thereof and held in different 'positions of adjustment by bolts 5 entered through slots in said fingers. The latter may be shifted in' or out to vary the'effective journaled on the reduced end 7 of a vertical shaft 9 which has its lowerend mounted` in a sleeve 11 in the base 1.3 of the machine Jframe. '.lhe table shaft 9 is yieldingly supported by a helical spring 15 encircling a reduced portion of said shaft and yconfined between upper and lower collars 17 thereon. 1

Beneath the table a .iold may be provided for folding a wrapper up about the lower portion of the shoes. This mold comprises a disk 19 having brackets 21'proj ecty ing radially therefrom and adj ustably held thereto by bolts 23 entered through elongated slots in said brackets. Mounted on the upturned ends oi' the bracket are supporting lingers 25 preferably of resilient material which are adapted to engage a wrapper and fold the same up smoothly about the lower, outer surface portion of the shoe or group of shoes as more fully hereinafter described. The brackets and fingers form a skeletonizcd, cup-shaped mold which may he readily adjusted to accommodate tires or articles of different sizes. The mold hasva hub 27 depending therefrom re- 'ceiving the table shaft 9 and journaled in a bearing 29 on the frame base.

The table and mold are adapted to be rotated for a. purpose more fully herein after described. ln Figs. 1, 5 and 9 is shown a suitable mechanism toaccomplish this including a worm gear 31 secured t0 the under face of the mold and adapted to bev driven by a tumbler-worm 33 (Fig. 10) fast on a shaft 35 journaled in bearings in a rocker bracket 37,4which bracket is fulcrumed on a horizontal shaft 41 extending the length of and journaled in bearings in the machine base. The worm is driven by a pinion 43 on the shaft-35 which meshes with. a pinion 44 in the shaft 41. At the left end (Fig. 5) of the shaft 41 is a gear 45 driven by pinion 47 of an electric motor t 49 mounted on the frame base.

llo rotate the mold and table at the times desired. the, rocker bracket may be adjusted to throw the worm into or out vof mesh with the worm gear. To accomplish this the bracket 37 may be connected by a link 51 (Fig. 5) with an eccentric pin 53 on the end of a shaft 55 journaled in brackets 57 on. the machine base. At one end of said shaft is ahandle 59 which'may be readily rocked to shift the tumbler-worm to positions where 'it is effective orv ineflfcctire to impart rotation from the motor 'to the table and mold as desired.

The table l is normally urged upward away from the mold by its supporting spring. 1When in this position it is free to swivel on its supporting shaft to permit ready rotative adjustment of the' table to facilitate positioningof articles thereon or for other purposes. When, however, the

table is pressed downward against the resistance of its supporting spring it should engage the mold so as to rotate therewith. To this end, the table and mold may be provided with interengaging lugs 61 Figs. 9 and 9u) adjacent their peripheries so that when they are brought in line with each other rotary movement of the mold will be positively imparted to the table.` These lugs may be wedge-shaped as shown to prevent them from limiting downward adjustment of the table toward the mold.

After the tireshoes have been placed on the table, they may be compressed or tensioned so that they may later expand and contribute to the tightness and smoothness of the wrapper. This compression is important, since during storage and shipment,

packages of wrapped shoes may be stored inpiles, and if not adequately preliminarily compressed the weight on the lower packages might loosen their wrappers, destroy the smoothness thereof and injure the same.

Means for compressing the tire shoes will next be described. To accomplish this an upper presser mold may be provided comprising a series of spring fingers 63 (Figs. 1, 2 and 3) secured to bars' 65 radially disposed on a ring 67 and adjustably connected to said bars by bolts 69 projecting through elongated slots in said bars. These fingers may be readily adjusted to conformto tire shoes or other articles of diiferent sizes. The ring 67 is connected to a second ring 71 and is spaced therefrom. Received between the two rings are rollers 73 carried by studs v75 of brackets 77 (Figs. 1 and 14). The two rings can thus rotate freely. The

brackets 77 .are bolted to guide fins79 on i` nuts 81, said fins being adapted to slide in vertical slots 83 (F ig. 5) formed in tubular columns These columns may have reduced ends 85El set in sockets in the frame base 13 as shown at the left of Fig. 1, and the upper ends of the columns have heads 86 (Figs. 1 and 4) connected by a horizontal bridge 87.'

For lowering and raising the presser mold, screw shafts 88 receiving the bracket carrying nuts 81 may bemounted in said tubular columns and have their upper ends journaled in said heads, and projecting beyond the same to receive gears 89 (Figs. 1, 4 and 8) the hubs of which are mounted fast on lsaid shafts and confine the latter against downward movement in said columns. The gears 89 mesh with pinions 91 on stud shafts 93 journaled in said heads 86 and having bevel gears 95 on their upper ends meshing with bevel gears 97 on ahorizontal shaft 99journaled in brackets 101. The shaft 99 projects beyond one of said brackets and haspulleys 103 and 105 (Figs. l and 4) loose thereon and an intermediate pulley 107 fast thereon. The pulley 103 is iso connected by a belt 109 with a pulley 111 (lig. 1) fast en the motor driven shaft 41 j rllhe pulley 105 is connected by belt 113 with said pulley 111. intermediate pulley 107 maybe opposite directions depending on e belt 109 or the belt 113 is ete. o control the belts ay shipper is provided comprising belt engaging portions 115 on a slide 117 shiftable axially in brackets 119 on said bridge: The shipper is connected to an arm 191 depending from a rock shaft 23 journaled in brackets projecting from one of the column heads 86. An arml125 on said shaft carries a dependingfrod 127 having handle 129. YPi/hen this handle is pulled downward it will move the shipper slide 11.7 to the left of Fig. 1 and throw the belt 113 on the intermediate pulley 'to rotate the shaft 99 and the screw 89 and cause the upper mold to move .i toward the group of shoes on the hen the upper mold has moved d suiiiciently to apply the desired i e repression to the shoes, the han- 199 r. ay be moved upward, thereby shiftie belt 113 from the tight pulley 107 its loose pulley 105, and thus arresting '1er downward movement of the mold. when it is desired to elevate the mold and release the compression, the handle 129 may be shifted farther upward, thereby adjusting the shipper 115 farther to the right and *l ing the uncrossed belt 109 to the tight ley 107. rlhis will rotate the shaft 99 l screw 33 in the opposite dion and cause the presser mold to move upward Aaway from the group of shoes. when the mold has traveled. upward sufriciently the handle 129 may be pulled downward, thereby shifting the belt 109-to the its loose pulley and causing the arf'b mold, v

my be provided for automatically the presser mold at the limits of watching the moldand arresting ne proper time. To this end Tvhich controls the shipper may l ar (Figs. 1 and 4) fast there om which hangs a rod 133 which passes :Jh a hole in an arm 135 (Fig. 1) projecting laterally from one or tne supporting braclrets 77 of the upper 'oresser mold referred to. The rod 133 y carry upper lower stop collars 13H and when the presser mold travels downv-Jard its arm 135 along the rod 133 until it engages :vial le lower stop collar 137. A slight further downward movement of the mold will drag the rod 133 downward, thereby shifting the belt 113 to the right from 'the tight pulley 107 to its loose pulley .105 and arresting the. further downward movement ofthe mold.

til

On the other hand, when the mold travels upward, its arm 135 will slide along the rod 133 until it engages the upper stop collar 137. Slight further upward movement will shift said rod upward and shift the belt 109 from the fast pulley 107 to its loose pulley 103.

By the mechanism described the presser mold may be shifted upward or downward by power and automatically arrested at the 4limits of its travel. ln some cases it may be desired to move the presser mold manually or it may be desired to adjust said mold manually as an operation supplemental to the power driven movement thereof. To accomplish this the gear 89 at the top of the screw shaft at the left of Figs. 1 and 4 may mesh with a pinion 139 fast on a shaft 141 journaled in an upper bearing 143 on one of the column heads 86, and in a lower bearing in a bracket 145 projecting laterally from said column. The lower end of said shaft carries a bevel gear 147 which meshes with a bevel gear 149 on a stud shaft journaled in said 'bracket 145 and having a hand wheel 151*` fast thereon. By turning said hand wheel rotary movement may be imparted through the shaft 99 and the bevel gears 95 and 97 to the screwhafts 88,thereby moving the presser mold upor down as desired. When this manual operation is being performed, of course the belts 109 and 113 should be on their loose pulleys so that they. will be inoperative to transmit motion to the shaft 99. A

In the course of the wrapping operation it is desired to release the presser mold to rallow the I wrapper to be spread over the surface covered by said mold. To hold "or clamp the group of shoes compressed during this operatiomrsuitable means may be provided typified herein as a dished plate 153 (Figs. 1, 2 and 3) having fingers 155 projecting radially therefrom and adjustably connected thereto by bolts 157 entered through elongated slots in said lingers. The latter may be adjusted out or in to accommodate shoes or other articles of different sizes. These lingers are adapted to engage the inner, upper surface portion of the top shoe substantially as shown in Fig. 18. To control the clamp plateit may be swiveled on the reduced end 159 of a rack bar 161 adapted to slide, but not rotate in a central boss 163 ofthe bridge 87.

Said clamp plate is raised and lowered by a pinion 165 (Figs. 1, 4 and 8) on a horizontal shaft 167 journaled in bearings in said bridge. bevel gear 169 fast on one end of said shaft'meshes with a bevel gear 171 fast on an end of a horizontal shaft 173 journaled in brackets 175 (Figs. 1 and 4) projecting laterally from said bridge. A bevel gear 177 on the opposite end of shaft 173 meshes with a bevel gear 179 fast on a vertical shaft 181 journaled in an upper bearing in the head 86 of the right-hand column in Fig. 1 and in a lower bearing in a bracket 183 (Figs. 6 and 7) projecting from said column. To rotate the shaft 181 a bevel, gear 185 thereon meshes with a bevel gear 187on a stud shaft journaled in said' Vis pivotally mounted o'n the bearing of the hand wheel shaft and is adapted to engagea ratchet wheel 193' fast on the hub of the hand wheel. This will lock the hand wheel against reverse rotation and securely hold the clamp plate-in position. When it is desired to release the clamp` plate a handle 191a on the pawl is rocked to trip the latter from its ratchet wheel and then the hand wheel may be readilyl rotated in a reverse direction to elevate the clamp plate.

To facilitate the raising and lowering of .the clamp plate a cable 195 may be secured to a pin 197 on said plate, lead upward over a guide pulley 199, thence extend outward over a guide pulley 201 and, .depending therefrom, pass through an eye of a counterbalance weight 203. Thel cable passes thence through another eye (Fig. 4) on said weight and up over similar pulleys 205 and 207 and downwardand itsopposite end is secured to the pin 197 referred to. The clamp plate is thus effectively counterbalanced so that it may be easily and quickly elevated and lowered as required. v Y

The mechanism already described operates, as -will be more fully explained hereinafter to wrap a sheet about they inner circumference and ends of the group of tires, folding the ends over tewardeach other at the outer circumference of the group.' To

. complete the wrapping and to seal the package, means may be provided for wrapping a strip of gummed paper or other suitable material circumferentially about thel group of shoes to unite the ends of the wrapping' the wiper belts are released from the pins sheet of the group. Y

Herein this means comprises a bracket 209 (Figs. 2, 5, 11 and 12) having a spindle 211 rising therefrom for receiving a spool 213 of gummed paper 214. The strip of paper may be led from the spool over a moistening device to the group of shoes. This meisteningdevice comprises a cylinder 215 mounted on the bracket 209 and containing waste 216 saturated with water. To meisten merely the margins of the gummed Strip the cylinder may, as shown in Fig. 12, have sections removed from a wall thereof to leave upper and lower apertures 217. A pad 219 of felt or other suitable material' may cover the apertures to prevent escape of the waste therethrough.

Presser rolls 221 may be mounted onan eccentric shaft 223 adjacent the moistening cylinder and opposite the apertures therein to facilitate proper guidance of the gummed strip. This shaft may have a handle 225 fast thereon for turning the rolls to vary the'space between the latter and said moistening device to produce the appropriate pressure of the strip against the meistening device. The eccentric shaft may be held in its different positions of adjustment by a set screw 227 threaded in the bearing of the shaft.

To press. the gummed stripagainst the package and insure secure adhesive engage-f ment o f said strip with the end of the wrapping there inay be provided wiper belts 229 (Figs. 4, 5, 13 and 15) of felt or other suitable material and of a width ucorresponding ,to that of the moistened -margins of the strip. These belts may have ends fastened to a rollerl 231 journaled on a shaft 233 mounted on the machine base. site free ends of said belts may be connected to a rod 234 having an veye 235 adapted, when the belts are not in use, to be hooked over a pin 236 (see at the right of Fig. 4) projecting' laterally from a post 237 on the machine base. When the wiper belts are in use they are released from the pin 236, the beltsare unwound from the.roller and the eye 235 is hooked over a pin 239, (at the left of Fig. 4) projecting laterally from a post 241 rising from the bracket 209 and which is at the opposite side vof the machine from the post 237 (see also Figs. 11 and 12). To tension the wiperv belts and automatically` rewind the same on the` roller 231 after they have been Aused to press the gummed strip .against the package, a cord 243 (Figs. 2, 3 and 15) may have one end connected to a spool 245 fast on the roller 231. The cord may be guided from said spool over a pulley 247 and have its epposlte end attached t0 a weight 249.. 1When the wiper belts are unwound from the roller 231, the cord 243 will be wound on the spool 245 and theweight will be lifted. )Vhen 239, the weight will un'wind the cord from the spool and/rewind said belts on said roller.

To facilitate opening of the package to release the tires, a pull cord may/be applied to the gummed strip. ".lo accomplish this an arm 250 (Figs. 4 and 5) is provided onthe machine base adjacent the gummed strip ,roll and supports a holder 250 fora lball vof twine. The twine from this ball may be led up between the moistening device (Fig. 12) and the eccentric roll shaft.

The oppol 'paper or other suitable material is placed upon the table 1. Then a ,wrapping in the' form of a tube of paper b, preferably crimped or otherwise formed to permit differential contraction or expansion to conform to the shape of the article wrapped, is drawn down over said core with its lower end portion spread out on the surface of the table 1. The upper end of the tube may be contracted by a rubber band c or other fastening applied thereto to prevent said end from being in the way of the next operation.

The shoes (Z to be wrapped are then placed on the table over said core and wrapping tube. T he wrapping sheet at this stage covers the inner circumference of the group and extends outwardly over the lower end surface but is not wrapped about the same. The crimpings of the sheet are opened out locally to permit a portion of the sheet to expand relatively to the rest and conform to the dimensions of the group of shoes.

Next the handle 129 is pulled to shift the belt 113 to thetight pulley 107, thereby rotating the screw shafts 88 and causing the presser mold 63 to travelvquickly down toward and to the top shoe of the group of shoes. The presser mold will continue on downward. and compress the shoes until its arm 135 engaUe-s .ie stop collar 13T and draws the rod m23 downward to shift the belt and stop further movement.

ln the course of the compression of the group of shoes, the table 1 will be depressed downward against the .resistance of its supporting spring 15 into the lower mold 25 17). .its a result, the outwardly projecting lower end portion of the wrapping` tube will be folded and pressed by the iingers b25 of said lower. mold up against the outer surface of the lower tire shoe.

Since the presser mold is of ring form it will allow the contracted end of the paper wrapping tube to project upward therethrough without interference therewith. The clamp plate 153 will not interfere with the tube since it was previously adiusted up out of the way. y y rlhe rubber band is then removed from the contracted end of thepaper wrapping and vsaid end is spread out over the presser mold. The hand 44wheel 189 is rotated quickly to lower the clamp plate 153 toward the 2group of shoes and into the upper end of the wrapping tube. v ltk continues on downward thereby causing its fingers 155 to press the wi fping tube against the inner, upper surface portion of the top shoe (Fig. 125). it is now in position to relieve the presser mold from the work of holding the shoes compressed.

Next the belt shipper handle 129 is shifted to lift the presser mold up away from the shoes toward the bridgewhere it will be automatically arrested a9. escribed Then the wrapping,- tube is spread out over 'the outer, upper surface of the top shoe and the presser mold is again lowered thereto (Fig. 19). lts lingers G3 will .,fold and press the wrapper tube down intok intimate engagement with the outer surface Of the upper shoe. 'l 'i The wrapper now covers the group of shoes with the exception of an exposed, circumferential portion between the upper and lower ends of the wrapper. To cover 'this the operator grasps an end of the gummed strip and draws the same from its supply spool, the strip being,` automatically mois'- tened and the pull cord applied thereto by the moistening device as the strip is drawn from said spool. The end of the strip is then stuck to the wrapper; the wiper belts are unwound from the roller and their ends attached to the pin 239; and then the handle 59 is rocked to shift the worm 33 into engagement with the worm gear 31. This initiates rotation of the table and the rotation thereof continues until the gummed strip completely encircles the package. The wiper belts engage a substantial portion of the circumference of the package and eXeroise their pressure on the gummed tape for suhicient length of time to allow the strip to adhere securely to the end wrapping. However, merely a short time is required since a. quick drying zgum is used on the strip.

Merely the margins of the gummed strip are moistened in order that the portion thereof intermediate said margins maywnot adhere to the shoes.

ln some cases the wrapping tube may pe made of sufficient length so that its end po 3 tions may meetv or overlap and complete the closure without the necessity for employment of the gummed strip described, although it is preferable to use the latter since it contributes to the production of a stronger wrapping and one which is more finished in appearance.

After the wrapping of the group of shoes is completed, the clamp disk and upper presser mold are lifted up away from the group of shoes, thereby permitting the tablesupporting springV to elevate the table to a point where it is substantially level with the free ends of the lingers Q5 of the lower mold. rlhe wrapped package with its core may then be slid from said table and the core removed.

The machine described will wrap the paper Vtightly about the group of shoes.l and which reinforcing strands are embedded as shown in my copending application, Serial No. 131,789, filed Nov. 16, 1916. The threads desirably extend longitudinally 'of the tube which is formed from the wrapping sheet and take the strain of the compressed tires.

From the description of the operation of the machine disclosed, the novel method of Wrapping articles which is a part of my invention and which the machine illustrates has been rendered clear. It is necessary to point out here only that, while the machine disclosed `is a convenient and desirable appliance for practising thel method, the method, may be practised by hand or with the aid of other mechanisms or appliances. Briefly stated the method contemplates wrapping an article by applying sheet covering material to the ends of the article, conforming thereto and presenting opposed ends at the sides and connecting said ends by a circumferentially disposed strip. More explicity to describe the particular manipulative steps here disclosed asan example of the method, it may be practised by applying a sheet l) to one circumference of an annular article; folding the ends of the sheet over the ends of the article and toward the other circumference, the sheet being conformed to the article by differential expansion, tor example, by local expansion or (':ontraction of suitable crimpings, and connecting the opposed ends at said other circumference.

Heretofore considerable ditHculty has been experienced in wrappmg and properly protectlng tire shoes and other articles during shipment and storage, but by my invention such articles may be quickly covered with a strong, protective, permanent wrapping ot smooth, finished appearance.

While the machine has been described more particularly with reference to `its use in wrapping tire shoes and like annular articles, it will be understood that the Yforms of the upper and lower molds may be varied and the machine may wrap various other articles as desired.
